For those HVAC contractors who offer duct-cleaning services, it can be a valuable part of their operations that not only helps their customers but also opens the door to more business. But, when it’s done improperly or unnecessarily, it can do more harm than good. That’s why those in the duct-cleaning industry are urging contractors to commit to proper training and ensure they’re looking at the bigger picture before adding these important services to their businesses.
In addition to aggravating allergies, spreading dust, and causing unpleasant odors, dirty ductwork can also negatively affect system performance, said Rick MacDonald, president at Armstrong Duct, Vent & Chimney in Manchester, New Hampshire, and a member of the National Air Duct Cleaners Association (NADCA) Board of Directors. “Dust, dirt, and other particulate will restrict air movement across cooling coils and fans, which can increase energy costs,” he explained. “Removing particulates like dust and dirt from the air-handling system will cut down on dusting, cut energy costs, and contribute to better IAQ.”
